Vim li cas cov tsheb ciav hlau tsis xeb?
Txoj kev tsheb ciav hlau raug los nag, av noo, qhov kub thiab txias hloov, thiab qee zaum txawm tias ib puag ncig ntsev, tseem nyob rau hauv kev ua haujlwm txhua hnub lawv tsis tshwm sim kom xeb sai li cov qauv hlau zoo tib yam. Qhov no tsis yog vim hais tias cov ntsia hlau tsis corrode, tab sis vim hais tias cov khoom siv rail xaiv, lub log-rail kev sib cuag tus cwj pwm, thiab kev tiv thaiv nto mechanisms ua rau qeeb pom xeb tsim, tshwj xeeb tshaj yog nyob rau hauv lub taub hau tsheb ciav hlau qhov twg log dov tsis tu ncua.
Cov kev tsheb ciav hlau niaj hnub no yog tsim los ntawm siab -carbon alloy rail hlau, xws liU71Mn, U75V, R260, R350HT,thiab900A, uas yog tsim tshwj xeeb los tiv thaiv hnav, qaug zog, thiab kev puas tsuaj saum npoo nyob rau hauv hnyav dov loads. Cov ntaub ntawv no tau siv dav hauv kev tsheb ciav hlau xws li UIC60, UIC54, 60E1, 132RE, 60kg, thiab 75kg hnyav rails.
Common Rail Steel Qib Ntiaj Teb:
| Qib | Standard / cheeb tsam | Kev sib xyaw ua ke (wt%) | Ntsiab nta & Daim ntawv thov |
| R260 | TS EN 13674-1 (Tebchaws Europe) | C: 0.67–0.80, Mn: 0.90–1.20, Si: Tsawg dua lossis sib npaug rau 0.50 | Base-qib tsheb ciav hlau; txias- dov; dav siv nyob rau nruab nrab - cov kab tsheb. Zoo weldability thiab nqi efficiency. |
| R350 HT | TS EN 13674-1 (Tebchaws Europe) | C: 0.75–0.85, Mn: 0.80–1.20, Cr: 0.20–0.50 | Kub-kho (online/offline); UTS Ntau dua lossis sib npaug ntawm 1100 MPa; 30-50% lub neej ntev dua R260. Txheem rau siab-ceev (TGV, ICE) thiab hnyav- cov kab tsheb thauj mus los. |
| Qib 260 | AREMA (North America) | C: ~0.77, Mn: ~1.0–1.2, Si: ~0.2 | Sib npaug rau R260; siv nrog rail seem xws li 115RE, 136RE. Feem ntau ntawm Class I freight networks. |
| Qib 350 | AREMA + Mill Specs (USA/Canada) | C: 0.78–0.83, Mn: 0.90–1.20, Cr: 0.2–0.6, + V/Nb (microalloyed) | TMCP or heat-treated; UTS ~1180–1280 MPa. For demanding curves, heavy axle loads (>33 tuj), thiab siab -tonnage txoj kev. |
| BH Rail (Baitic) | JIS E 1101 (Nyiv), tau txais kev pom zoo hauv EU / Is Nrias teb | C: 0.65–0.80, Mn: 1.0–1.4, Cr/Mo/Ni (yeem, zeb- tshwj xeeb) | Bainitic microstructure; siab zog (UTS ~ 1250-1350 MPa) + superior puas toughness. Siv rau ntawm Shinkansen nkhaus thiab siab - hnav ntu. |
| ua 71mn | GB / T 2585 (Tuam Tshoj) | C: 0.65–0.77, Mn: 1.10–1.40, Si: 0.15–0.35 | Ua haujlwm-hardening carbon-manganese rail; Txheem rau 50kg / m, 60kg / m rails ntawm Suav mainlines. Piv rau R260 / R350 hauv kev ua haujlwm. |
| U75V | GB / T 2585 (Tuam Tshoj) | C: 0.67–0.77, Mn: 0.70–1.00, V: 0.04–0.12 | Vanadium{0}}microalloyed; siab zog & qaug zog tsis kam tshaj U71Mn. Rau siab -ceev (piv txwv li, Beijing-Shanghai HSR) thiab hnyav -cov kab. |
Nruam Log Sib Txuas Tshem Tawm Nto Hlau Los Ntawm Rail Heads
Feem ntau pom ib feem ntawm txoj kev tsheb ciav hlau yog lub taub hau tsheb ciav hlau, uas yog nyob rau hauv kev sib cuag nrog cov hlau log. Txhua lub tsheb ciav hlau dhau los ua rau muaj kev ntxhov siab heev thiab micro- zawv zawg, uas tshem tawm cov txheej txheem oxidation ntxov ntxov ua ntej nws yuav loj hlob mus rau hauv cov txheej xeb tuab. Qhov no yog vim li cas txawm tias nyob hauv thaj chaw ntub dej, qhov chaw khiav ntawm UIC60 R260 rails lossis 60kg U71Mn rails feem ntau zoo li ci thiab polished, thaum lub teeb xeb tsuas yog pom hauv lub vev xaib thiab lub hauv paus qhov twg lub log tsis kov.
Cov nyhuv polishing no tseem ceeb tshwj xeeb tshaj yog nyob rau hauv siab - txoj kev tsheb khiav xws li metro systems thiab freight mainlines siv UIC60, 132RE, los yog EN 60E1 rails, qhov twg cov log tsheb tsis tu ncua tu lub tsheb ciav hlau qhov chaw. Rau kev lag luam lem nrog qis qis, xws li mining rails (22kg ua, 30kg, 24kg, 18kg) lossis warehouse flat bar rails, deg oxidation yuav tshwm sim yog tias cov tsheb ceev tsawg, yog vim li cas xaiv cov khoom siv thiab kev tiv thaiv kev kho mob ua qhov tseem ceeb hauv cov cheeb tsam no.
